Martinez fled the scene at Washington and Northampton streets in Boston. Witnesses gave her license plate number to police.

Pullum was rushed to Boston Medical Center following the 9 p.m. crash. She was pronounced dead at the hospital.

According to prosecutor Jennifer OKeeffee, when officers knocked at Martinez's Dorchester home, "she stated, 'I know why you are here, I panicked.'"

OKeeffee told the judge in Roxbury District Court, "She stated she was not wearing some prescription glasses that she was supposed to be wearing so that her vision may have been impaired, that she was simply very afraid which is why she left the scene of the accident."

Pullum, 63, lived near the accident scene. Her niece Keyanna Williams said she was "probably walking home."

Pullum, a grandmother, has one son and a large extended family. Several of the victim’s family members wept during the short court proceeding.

Her family called her a "wonderful mother, great person. She will be missed by family and many friends."

Martinez faces charges of motor vehicle homicide. Bail was set at $1,000. She is due back in court Oct. 23.
